[0019] The present invention has the following beneficial effects:

[0020] (1) For the assembly line for machining an elevator traction machine of the present invention, when in use, a semi-finished product of the traction machine is placed on the strip-shaped plate. At this time, the driving motor and the driving roller are started. The driving roller drives the belt to rotate. The belt drives a plurality of round rods to rotate. The round rods drive the strip-shaped plate to rotate. The strip-shaped plate drives the semi-finished product of the traction machine to move towards the direction close to the mounting frame. When the semi-finished product of the traction machine contacts the L-shaped internal thread block, the strip-shaped plate continues to rotate. At this time, the semi-finished product of the traction machine temporarily stops moving. Then, a robotic arm is used to machine and assemble the semi-finished product of the traction machine. At this time, the driving motor rotates forward. The driving motor drives the double trapezoidal reciprocating screw to rotate. The double trapezoidal reciprocating screw drives the two L-shaped internal thread blocks to move towards each other. The L-shaped internal thread blocks leave the threads on the double trapezoidal reciprocating screw and contact the push plate. At this time, the telescopic spring undergoes a compressive deformation. The push plate顶住 the L-shaped internal thread blocks under the elastic force of the telescopic spring, so that the L-shaped internal thread blocks are in a semi-disengaged state from the threads. At this time, the L-shaped internal thread blocks no longer move, which is convenient for the L-shaped internal thread blocks to limit the semi-finished product of the traction machine and convenient for assembling the semi-finished product of the traction machine. After the semi-finished product of the traction machine is assembled, the motor is reversed. The telescopic spring will push the push plate to push the L-shaped internal thread blocks under the elastic force so that they move onto the threads of the double trapezoidal reciprocating screw again. The double trapezoidal reciprocating screw drives the two L-shaped internal thread blocks to move away from each other. When the L-shaped internal thread blocks leave the traction machine, the traction machine will continue to be transported towards the direction close to the mounting frame under the action of the strip-shaped plate. When the two L-shaped internal thread blocks move away from each other and reach the outermost ends of the two threads, the two L-shaped internal thread blocks will reciprocate. At this time, the two L-shaped internal thread blocks will approach again and get ready for limiting the semi-finished product of the traction machine next time;

[0021] (2) In the process of the continuous rotation of the strip-shaped plate, the traction machine leaving the L-shaped internal threaded block will come into contact with the second adjusting plate. At this time, the traction machine will pause moving again, and then the traction machine will be tested. If the test result is qualified, the electric telescopic rod will be started. The electric telescopic rod drives the toothed plate to move away from the driving motor. The toothed plate will drive the gear to rotate, the gear drives the rotating shaft to rotate, and the rotating shaft drives the second adjusting plate to contact the left inner wall of the assembly base. Correspondingly, the first adjusting plate will contact the right inner wall of the assembly base near the driving motor. At this time, the strip-shaped plate will drive the traction machine into the guiding chute of the qualified channel under the limitation of the second adjusting plate and the corresponding first adjusting plate, and slide from the guiding chute to the guiding rail and finally enter the collection box for loading qualified traction machines. If the test result of the traction machine is unqualified, the corresponding unqualified traction machine will enter the collection box for loading unqualified ones, which is convenient for classifying the traction machines;

[0022] (3) In the process of the rotation of the double trapezoidal reciprocating screw of the assembly line for processing elevator traction machines of the present invention, the reciprocating screw will be driven to rotate synchronously under the action of the transmission wheel and the transmission belt. The reciprocating screw will drive the fan blade to rotate. When the driving motor rotates forward, the fan blade rotates forward, and the forward rotation of the fan blade generates a blowing force. The wind enters the wind hood through the through groove and the connecting groove, and then blows out from the through hole on the wind hood to blow the position of the stationary traction machine semi-finished product, avoiding overheating of the traction machine semi-finished product caused by long-term friction between the strip-shaped plate and the traction machine semi-finished product, which affects the processing quality of the traction machine semi-finished product. When the driving motor rotates reversely, the fan blade rotates reversely, and the reverse rotation of the fan blade generates a suction force. The suction force will suck the heat generated by the through hole at the position of the stationary traction machine semi-finished product, and also produce the effect of heat dissipation and temperature reduction. When the reciprocating screw rotates, it will drive the scraping strip to rotate, and the scraping strip will remove the dust and impurities on the surface of the air box during the rotation process. Correspondingly, the reciprocating screw will drive the internal threaded scraper to move reciprocally during the rotation process, and the reciprocating movement of the internal threaded scraper will clean the dust and impurities on the surface of the wind hood, so as to ensure that the through hole on the wind hood will not be blocked and make the temperature reduction effect more stable;

[0023] (4) When the traction machine slides into the collection box in the assembly line for processing elevator traction machines of the present invention, due to inertia, the traction machine will come into contact with the contact plate. The contact plate will drive the T-shaped sliding rod to move towards the driving motor. At this time, the shock-absorbing spring will generate a tensile deformation. Correspondingly, the shock-absorbing spring will buffer the traction machine to avoid the traction machine directly hitting the inner wall of the collection box and causing damage. During the movement of the T-shaped sliding rod towards the driving motor, it will drive the C-shaped rod to move, the C-shaped rod drives the strip-shaped mounting plate to move, and the strip-shaped mounting plate will drive a number of limit closing rods to move synchronously. The limit closing rods will open the discharge port. At this time, the opening of the discharge port is convenient for taking out the assembled traction machine for maintenance or storage, improving the flexibility and convenience of the assembly line.

[0037] Please refer to Figure 1-Figure 8 As shown in the figure, the present invention is an assembly line for the processing of elevator traction machines, including an assembly base 1. Two driving rollers 2 are rotatably installed on the assembly base 1. Two belts 3 are sleeved on the two driving rollers 2. Limiting grooves 4 are respectively opened on the inner walls of the two sides of the assembly base 1 close to each other. It further includes:

[0038] A limiting mechanism 5, the limiting mechanism 5 includes an L-shaped internally threaded block 506, a moving assembly, the moving assembly is used to drive the L-shaped internally threaded block 506 to move, a limiting assembly, and the limiting assembly is used to limit the L-shaped internally threaded block 506;

[0039] The moving assembly includes a plurality of round rods 501 fixedly installed through the two belts 3. The mutually remote ends of the plurality of round rods 501 respectively extend into the two limiting grooves 4. Strip plates 502 are respectively fixedly installed on the plurality of round rods 501. An installation groove 503 is opened in the assembly base 1. A double trapezoidal reciprocating screw 504 is rotatably installed in the installation groove 503. The double trapezoidal reciprocating screw 504 penetrates through the assembly base 1;

[0040] The limiting assembly includes a driving motor 505 fixedly mounted on the right side of the assembly base 1, the output shaft of the driving motor 505 is fixedly connected to the double trapezoidal reciprocating screw 504, and two L-shaped internal thread blocks 506 are threadedly sleeved on the double trapezoidal reciprocating screw 504, and the ends of the two L-shaped internal thread blocks 506 that are close to each other extend outside the assembly base 1.

[0041] like Figure 3 As shown, two sleeve plates 507 are fixedly installed on the top inner wall of the mounting groove 503, and telescopic springs 508 are fixedly installed on the sides of the two sleeve plates 507 away from each other, and push plates 509 are fixedly installed on the sides of the two telescopic springs 508 away from each other, and the sides of the two push plates 509 away from each other are in contact with two L-shaped internal thread blocks 506, respectively, and the double trapezoidal reciprocating screws 504 pass through the two sleeve plates 507 and the two push plates 509.

[0042] The L-shaped internal thread block 506 will leave the threads on the double trapezoidal reciprocating screw 504 and contact the push plate 509. At this time, the telescopic spring 508 undergoes compression deformation, and the push plate 509 will support the L-shaped internal thread block 506 under the elastic force of the telescopic spring 508.

[0043] like Figure 3 and Figure 5 As shown, a reciprocating screw 510 is rotatably installed on the assembly base 1, and a transmission wheel 511 is fixedly sleeved on the reciprocating screw 510 and the double trapezoidal reciprocating screw 504 respectively, and a transmission belt 5101 is sleeved on the two transmission wheels 511. An internal threaded scraper 512 is threadedly sleeved on the reciprocating screw 510, and two triangular grooves 513 are provided on the top of the internal threaded scraper 512. A limiting rod 514 is fixedly installed on the assembly base 1, and the limiting rod 514 penetrates the internal threaded scraper 512 and is slidably connected to the internal threaded scraper 512. A bellows 515 is rotatably sleeved on the transmission wheel 511, and the right side of the bellows 515 is fixedly connected to the assembly base 1, and a scraping strip 516 is fixedly sleeved on the transmission wheel 511, and the right side of the scraping strip 516 is in contact with the bellows 515.

[0044] When the reciprocating screw 510 rotates, the scraper bar 516 is driven to rotate. The scraper bar 516 removes dust and impurities on the surface of the bellows 515 during the rotation process. Correspondingly, the reciprocating screw 510 drives the internal thread scraper 512 to reciprocate during the rotation process.

[0045] like Figure 7 As shown, a heat dissipation mechanism 6 is provided on the reciprocating screw 510, and the heat dissipation mechanism 6 includes a fan blade 601 fixedly mounted on the reciprocating screw 510, a through slot 602 is opened in the assembly base 1, and the drive motor 505 is communicated with the through slot 602, and a connecting slot 603 is opened in the assembly base 1, and the through slot 602 is communicated with the connecting slot 603.

[0046] The reciprocating screw 510 drives the fan blades 601 to rotate. When the driving motor 505 rotates forward, the fan blades 601 rotate forward, and the forward rotation of the fan blades 601 generates a blowing force, and the wind enters the wind cover 604 through the through slots 602 and the connecting slots 603.

[0047] like Figure 3 As shown, a wind shield 604 is fixedly mounted on the assembly base 1 , the connecting groove 603 is communicated with the wind shield 604 , a plurality of through holes 605 are opened on the top of the wind shield 604 , and the bottom of the internal thread scraper 512 is in contact with the wind shield 604 .

[0048] The reciprocating movement of the internal thread scraper 512 can clean the dust and impurities on the surface of the wind cover 604, thereby ensuring that the through hole 605 on the wind cover 604 will not be blocked, making the cooling effect more stable.

[0049] like Figure 8 As shown, an adjustment mechanism 7 is provided on the top of the assembly base 1, and the adjustment mechanism 7 includes a mounting frame 701 fixedly mounted on the top of the assembly base 1, a rotating shaft 702 is rotatably mounted on the top inner wall of the mounting frame 701, two first adjustment plates 703 are fixedly mounted on the bottom end of the rotating shaft 702, and a second adjustment plate 704 is fixedly mounted on the bottom end of the rotating shaft 702, and the second adjustment plate 704 and the two first adjustment plates 703 are distributed in an isosceles triangle shape.

[0050] The rotating shaft 702 drives the second adjustment plate 704 to contact the left inner wall of the assembly base 1 , and the corresponding first adjustment plate 703 contacts the right inner wall of the assembly base 1 close to the driving motor 505 .

[0051] like Figure 8 As shown, an electric telescopic rod 705 is fixedly mounted on the right inner wall of the mounting frame 701 , a toothed plate 706 is fixedly mounted on the output end of the electric telescopic rod 705 , a gear 707 is fixedly sleeved on the rotating shaft 702 , and the gear 707 is meshed with the toothed plate 706 .

[0052] If the test result is qualified, the electric telescopic rod 705 is started, and the electric telescopic rod 705 drives the tooth plate 706 to move away from the driving motor 505, and the tooth plate 706 drives the gear 707 to rotate.

[0053] like Figure 5 and Figure 8 As shown, two guiding inclined grooves 708 are provided on the assembly base 1 , and guiding inclined rails 709 are fixedly installed on the left and right sides of the assembly base 1 , respectively, and collecting boxes 710 are fixedly installed on the backs of the two guiding inclined rails 709 .

[0054] The strip plate 502 drives the traction machine to enter the guiding inclined groove 708 of the qualified channel under the limitation of the second adjusting plate 704 and the corresponding first adjusting plate 703, and slides from the guiding inclined groove 708 to the guiding inclined rail 709 and finally enters the collection box 710 for loading qualified traction machines. If the test result of the traction machine is unqualified, the corresponding unqualified traction machine will enter the collection box 710 for loading unqualified ones, which is convenient for classifying the traction machines.

[0055] As Figure 5 shown, damping mechanisms 8 are respectively arranged on the two collection boxes 710. The damping mechanism 8 includes a T-shaped sliding rod 801 slidably installed through the collection box 710. A contact plate 802 is fixedly installed on the front surface of the T-shaped sliding rod 801. A damping spring 803 is sleeved on the T-shaped sliding rod 801. The front end of the damping spring 803 is fixedly connected to the contact plate 802, and the end of the damping spring 803 is fixedly connected to the T-shaped sliding rod 801.

[0056] When the traction machine slides into the collection box 710, due to inertia, the traction machine will contact the contact plate 802. The contact plate 802 will drive the T-shaped sliding rod 801 to move towards the direction close to the drive motor 505. At this time, the damping spring 803 will generate a tensile deformation, and accordingly, the damping spring 803 will buffer the traction machine to prevent the traction machine from directly hitting the inner wall of the collection box 710 and causing damage.

[0057] As Figure 5 shown, a discharge port 804 is opened on the right side of the collection box 710. A C-shaped rod 805 is fixedly installed on the back surface of the T-shaped sliding rod 801. A strip-shaped mounting plate 806 is fixedly installed on the front surface of the C-shaped rod 805. A plurality of limit closing rods 807 are fixedly installed on the front surface of the strip-shaped mounting plate 806. The plurality of limit closing rods 807 all slide and extend into the discharge port 804 and are all in contact with the discharge port 804.

[0058] During the process of the T-shaped sliding rod 801 moving towards the drive motor 505, it will drive the C-shaped rod 805 to move. The C-shaped rod 805 drives the strip-shaped mounting plate 806 to move. The strip-shaped mounting plate 806 will drive the plurality of limit closing rods 807 to move synchronously. The limit closing rods 807 will open the discharge port 804. At this time, the opening of the discharge port 804 is convenient for taking out the assembled traction machine for maintenance or storage, improving the flexibility and convenience of the assembly line.

[0059] When in use, the semi-finished product of the traction machine is placed on the strip plate 502, and the driving motor 505 and the driving roller 2 are started at this time. The driving roller 2 will drive the belt 3 to rotate, and the belt 3 will drive a number of round rods 501 to rotate, and the round rods 501 will drive the strip plates 502 to rotate, and the strip plates 502 will drive the semi-finished product of the traction machine to move in the direction close to the mounting frame 701. When the semi-finished product of the traction machine contacts the L-shaped internal thread block 506, the strip plate 502 continues to rotate. At this time, the semi-finished product of the traction machine temporarily stops moving, and then the mechanical arm is used to process and assemble the semi-finished product of the traction machine. At this time, the driving motor 505 rotates forward, and the driving motor 505 drives the double trapezoidal reciprocating screw 504 to rotate, and the double trapezoidal reciprocating screw 504 drives the two L-shaped internal thread blocks 506 to move towards each other. When the double trapezoidal reciprocating screw 504 is moved, the L-shaped internal thread block 506 will leave the threads on the double trapezoidal reciprocating screw 504 and contact the push plate 509. At this time, the telescopic spring 508 is compressed and the push plate 509 will support the L-shaped internal thread block 506 under the elastic force of the telescopic spring 508, so that the L-shaped internal thread block 506 is in a semi-disengaged thread state. At this time, the L-shaped internal thread block 506 no longer moves, which is convenient for the L-shaped internal thread block 506 to limit the semi-finished product of the traction machine and to facilitate the assembly of the semi-finished product of the traction machine. After the semi-finished product of the traction machine is assembled, the motor is reversed. The telescopic spring 508 will cause the push plate 509 to push the L-shaped internal thread block 506 to move to the threads of the double trapezoidal reciprocating screw 504 again under the elastic force. The double trapezoidal reciprocating screw 504 will drive the two L-shaped internal thread blocks 50 6 move away from each other. After the L-shaped internal thread block 506 leaves the traction machine, the traction machine will continue to be transported towards the mounting frame 701 under the action of the strip plate 502. When the two L-shaped internal thread blocks 506 move away from each other and reach the farthest ends of the two threads, the two L-shaped internal thread blocks 506 will reciprocate. At this time, the two L-shaped internal thread blocks 506 will approach each other again and prepare for the next limit of the traction machine semi-finished product. During the continuous rotation of the strip plate 502, the traction machine that leaves the L-shaped internal thread block 506 will contact the second adjustment plate 704. At this time, the traction machine will stop moving again, and then the traction machine will be tested. If the test result is qualified, the electric telescopic rod 705 will be started, and the electric telescopic rod 705 will drive the tooth plate 706 to move away from the drive motor 505. The gear plate 706 drives the gear 707 to rotate, and the gear 707 drives the rotating shaft 702 to rotate. The rotating shaft 702 drives the second adjusting plate 704 to contact the left inner wall of the assembly base 1, and the corresponding first adjusting plate 703 contacts the right inner wall of the assembly base 1 close to the driving motor 505. At this time, the strip plate 502 drives the traction machine to enter the guide inclined groove 708 of the qualified channel under the limit of the second adjusting plate 704 and the corresponding first adjusting plate 703, and slide from the guide inclined groove 708 to the guide inclined rail 709 and finally enter the collection box 710 loaded with qualified traction machines. If the result of the traction machine test is unqualified, the corresponding unqualified traction machine will enter the collection box 710 loaded with unqualified traction machines, which is convenient for classifying the traction machines;

[0060] During the rotation of the double trapezoidal reciprocating screw 504, the reciprocating screw 510 will be driven to rotate synchronously under the action of the transmission wheel 511 and the transmission belt 5101. The reciprocating screw 510 will drive the fan blade 601 to rotate. When the driving motor 505 rotates forward, the fan blade 601 rotates forward, and the forward rotation of the fan blade 601 generates a blowing force. The wind enters the wind hood 604 through the through groove 602 and the connecting groove 603, and then blows out from the through hole 605 on the wind hood 604 to blow the position where the semi-finished product of the traction machine stays, so as to avoid overheating of the semi-finished product of the traction machine caused by long-term friction between the strip plate 502 and the semi-finished product of the traction machine, which affects the processing quality of the semi-finished product of the traction machine. When the driving motor 505 rotates reversely, the fan blade 601 rotates reversely, and the reverse rotation of the fan blade 601 generates a suction force. The suction force will extract the air at the position of the semi-finished product of the traction machine through the through hole 605 to absorb the generated heat, and also produce the effect of heat dissipation and temperature reduction. When the reciprocating screw 510 rotates, it will drive the scraping strip 516 to rotate, and the scraping strip 516 will remove the dust and impurities on the surface of the air box 515 during the rotation process. Correspondingly, the reciprocating screw 510 will drive the internal thread scraper 512 to reciprocate during the rotation process, and the reciprocating movement of the internal thread scraper 512 will clean the dust and impurities on the surface of the wind hood 604, so as to ensure that the through hole 605 on the wind hood 604 will not be blocked and make the cooling effect more stable; when the traction machine slides into the collection box 710, due to inertia, the traction machine will contact the contact plate 802, and the contact plate 802 will drive the T-shaped slide bar 801 to move towards the direction close to the driving motor 505. At this time, the shock-absorbing spring 803 will produce a tensile deformation, and correspondingly, the shock-absorbing spring 803 will buffer the traction machine to avoid the traction machine directly hitting the inner wall of the collection box 710 and causing damage. During the movement of the T-shaped slide bar 801 towards the driving motor 505, it will drive the C-shaped rod 805 to move, and the C-shaped rod 805 will drive the strip-shaped mounting plate 806 to move. The strip-shaped mounting plate 806 will drive a plurality of limit closing rods 807 to move synchronously, and the limit closing rods 807 will open the discharge port 804. At this time, the opening of the discharge port 804 facilitates the removal of the assembled traction machine for maintenance or storage, improving the flexibility and convenience of the assembly line.
